Tell us what’s happening:
My code runs perfectly
and fulfills all the requirements on VS Code and also on playcode io, but it fails the tests here. What is happening? what am I doing wrong?
**Your code so far**
// The global variable
const bookList = ["The Hound of the Baskervilles", "On The Electrodynamics of Moving Bodies", "Philosophiæ Naturalis Principia Mathematica", "Disquisitiones Arithmeticae"];
// Change code below this line
function add(arr, bookName) {
newArr = [...arr];
newArr.push(bookName);
//const a = arr.concat(newArr)
return newArr;
// Change code above this line
}
// Change code below this line
function remove(arr, bookName) {
const newArr = [...arr]
const book_index = arr.indexOf(bookName);
if (book_index >= 0) {
newArr.splice(book_index, 1);
return newArr;
// Change code above this line
}
}
